No issues at all here. I've bought multiple items over the past few days using PayPal without any issues. 

I thought I'd try using Visa, and that's just now gone through fine as well.

Edit: Just a thought... do you have a debit/credit card saved for your purchases? If you don't, that could be creating the issue. Mine is saved and the payment button has a closed padlock icon

Yes I've stored card. Been buying and selling for couple years. It's still not working 😞 no answer from eBay tech

 either. 

Thank You ! Not just me then lol. You can go to eBay via internet and log in but not ebayau just ebay.com . It works for me going via usa . Australia is clearly down . Hope they fix it soon . Tis a pain 🤣

Having a Parcel Collect or Parcel Locker address as "Primary" will also cause the payment button to be greyed out. 

The work around for Parcel Collect is to set a different address as "Primary", then edit the saved Parcel Collect address to remove the space between the two blocks of 5 digits.

After the edit, it can then be set as "Primary" again, and the payment button will become active. 

Thank you ! Tech hasn't replied to me I guess they're inundated with same issue complaint. 

Used browser logged in ebayau. Same issue . Logged in ebay not au and it works . Clearly Aussie issue. Can purchase but via USA ebay . Thanks for the reply and help 🙏🏼
